Buffer solutions are liquids that maintain a stable pH value even when acids or bases are added. They consist of a weak acid and its conjugate base (or vice versa).
Why are they needed?
- Calibration of measuring devices: For accurate pH measurements.
- Environmental analysis: To monitor the pH of water samples.
- Food industry: To control the pH in food products.
- Pharmaceutical applications: To produce stable medications.
- Laboratories and research: To maintain consistent pH conditions in experiments.
Buffer solutions are crucial for keeping the pH constant and ensuring precise measurements and processes.
